The kmixer.sys process is the executable file for the Kernel-Mode Audio Components, or simply KMixer, a Windows driver or WDM used for audio playback and sound filtering. KMixer creates a mixed stream that a filtering device can handle. The streams can have different wave formats with different rates, channel counts, and sample sizes. Samples are expressed in integer or a floating-point value. KMixer also performs format conversion without mixing in a capture stream. The KMixer system driver, also called KS filter, does the following: • Multiple-PCM audio streams mixing • High-definition format conversion • Bit-depth conversion • Configuration of speakers and channel mapping • Supports IEEE and PCM floating-point data • Supports stereo and mono data formats from 8-bit format to 16-bit format • With bit depth greater than 16-bit • Has multi-channel formats in more than 2 channels • 3-dimensional head-related transfer function (HRTF) • Has sample-rate and mixing conversion rates

Most non-system processes that are running can be stopped because they are not involved in running your operating system. kmixer.sys. is used by WDM Audio, If you shut down kmixer.sys, it will likely start again at a later time either after you restart your computer or after an application start. To stop kmixer.sys, permanently you need to uninstall the application that runs this process which in this case is WDM Audio, from your system.

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.

The ReviverSoft experts have not yet reviewed kmixer.sys

A process usually a part of an installed application such as WDM Audio, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.

We have not received any complaint about this process having higher than normal impact on PC performance. If you have had bad experiences with it please let us know in a comment below and we will investigate it further.

The first thing you should do if kmixer.sys. is causing errors on your computer is to run a Windows registry scan with Registry Reviver If you are still seeing errors after this you should uninstall the program that kmixer.sys, belongs to, in this case WDM Audio
